thankyou. i realise that i have several options to install apps. however i want to do it a particular way. What i am after is a working command which will find all the the .cmd files in a certain directory and run each one seperately. I will also then do the same with all the .reg files in a certain directory and again with all my self created .msi files. This way i dont have to keep editing the autounattend.xml, i can just drop new files into my install directories and re-create my iso. Can anyone help? I tried a few commands after digging out my xp install.cmd but they all failed.
